A 13-year-old Atlanta girl is being charged as an adult in the death of her 2-year-old sister. According to police, Tyasia Jackson stabbed Sasha Lamaya Ray multiple times because the toddler caught Tyasia with a boy inside the house as their parents were at work and told a neighbor. Sasha's dad (who is Tyasia's step-father) told the local CBS affiliate, "[Tyasia] made all the other kids go upstairs and then she stabbed [Sasha] by the back door. Put her outside came back in the house, cleaned up the blood, changed clothes then came outside and started looking for her with everybody else." Sad.
